اندازه گیری کلینیکی ثبات ایمپلنت به روش آنالیز فرکانس انعکاسی برروی دو سیستم ایمپلنت Astra tech و ITI
مقدمه: آنالیز فرکانس انعکاسی (RFA)، اندازه گیری کلینیکی ثبات ایمپلنت و اوستئواینتگریشن را میسر می سازد و توسط یک شاخص کمی بنام شاخص ثبات ایمپلنت (ISQ) که بین 1 تا 100 متغیر است ارایه می شود. در مطالعه حاضر ثبات ایمپلنت در دو سیستم ITI و Astra tech در دوره التیام مقایسه و فاکتورهای موثر بر آن تعیین شد. مواد و روش ها:در این مطالعه کارآزمایی بالینی که مسائل اخلاقی آن مورد تایید کمیته اخلاق دانشگ...

متن کاملImplant adaptation of stock abutments versus CAD/CAM abutments: a radiographic and Scanning Electron Microscopy study.
INTRODUCTION The study evaluated a null-hypothesis of no differences of fit between stock abutments and CAD/CAM titanium, gold sputtered and zirconia abutments when examined for radiographic adaptation and Scanning Electron Microcopy (SEM) at their inner aspect. The agreement between microscopic and radiographic fit was also assessed. METHODS Implants (Osseospeed, Astra Tech, Mölndal, Sweden)...
